Abstract

L'invention concerne un appareil et système médical permettant de déterminer une estimation du contact qui incorpore un cathéter muni d'un corps allongé possédant une extrémité proximale, une extrémité distale opposée à l'extrémité proximale, et qui définit une lumière d'injection et une lumière d'évacuation, une membrane expansible définissant une chambre de refroidissement disposée à un certain point le long du corps allongé, la chambre de refroidissement étant en communication fluidique avec la lumière d'injection et la lumière d'évacuation, et un élément d'estimation du contact qui peut être une sonde de température située à proximité de la lumière de retour du liquide de refroidissement pour mesurer une température interne de la chambre. Selon l'invention, le système peut incorporer le cathéter, une console pourvue d'une alimentation en fluide, un chemin d'évacuation et au moins un mécanisme de contrôle accouplé d'une manière opérationnelle à la sonde de température pour traiter un signal de température provenant de la sonde de température. L'appareil et système de l'invention peut aussi posséder de multiples électrodes pour mesurer et traiter les diverses impédances afin de déterminer l'estimation du contact.
